I spoke to a person today very high up in the food chain at Horizon today regarding 8411's

The 8411 problem was explained to me to be a heli application problem. NOT AN AIRCRAFT PROBLEM.

This is what he told me:

"It is really a combination of vibration and flight loads in helis. There are a lot of factors, but it is basically working the servo hard enough that it is getting the motor too hot. This heat in the motor is causing the problems. The 8311 motor has a higher ohm value which in turn reduces the torque, and a combination of these 2 things eliminates some heat build up."


If you feel that you need a replacement for an 8411 that you have in a aircraft, they will replace it for you. But, they dont feel its needed.
